MULTIPLE-MAGAZINE TYPOGRAPHICAL CGMPOSING-MACHINE.

Application filed December 5, 1916.

To all whom it may concern:

Be 1t known that I, CARL MUEHLEISEN, a cltizen of the United States of America, re-

' siding at Chausseestrasse 23, Berlin N. 4, in

the Empire of Germany, have invented new and useful Improvements in lVlultiple-Maga zine Typographical Composing-Machines, of which the following is a specification.

This invention relates to typographical composing machines such as those known commercially under the trade mark f Linotype and kindred machines, and particularly it relates to those machines which are provided with a column of superposed magazines adjustable to bring any of the latter into operative or composing position, and in which the escapements are actuated by rods which, before and after the magazines are so adjusted, must be moved respectively out of and into the path followed by the magazines or escapements during such adjustment.

It has heretofore been proposed to effect the raising and lowering, hereinafter termed shifting, of the column of magazines by means of crank-actuated screw gear the crank being rotated by hand and provided with special means whereby the escapement rods could be moved as aforesaid, before and after the shifting of the magazines.

In the just mentioned arrangement, as well as in all others previously suggested, the aforesaid movement of the escapement rods has involved a distinct action on the part of the operator, for example, axially moving the crank shaft or operating a special lever, and the object of the present invention is to provide means of such construction that the said movement of the escapement rods and the shifting of the magazines are both effected by a single act on the part of the operator, which does not call for any attention being especially directed to either independently of the other.

The invention may be said to consist essentially in the employment, for shifting the magazines, of a worm or screw the thread of which is so formed that, during the period at which the escapement rods are to be moved out of and into the aforesaid path, no motion will, by the rotation of such screw, be imparted to the magazines, and vice versa.

The invention will now be described by reference to the accompanying drawings in which 2- Figure 1 is a side elevation. of a six-maga Specification of Letters Patent.

Patented Apr. 10, 1917.

Serial No. 135,252.

zine machine provided with the improved mechanism according to the present invention; 7

Fig. 2 is a sectional elevation of a part of the magazine-shifting gear;

Fig. 8 is a vertical section on or about the line 33 of Fig. 2, and

Fig. 4 is a view of the means for moving the escapement rods out of and into operative position.

In these drawings, a; is the machine frame, 7) the magazines supported upon a common frame 0, to which latter are secured toothed bars or racks (Z'meshing with spur wheels 0. The wheels 6 are fast upon shafts f which are correspondingly rotated by worm gearing, for which purpose the said shafts have secured thereon disks 9 having studs or rollers g angularly distributed thereon at uniform distances apart and with which studs the worms h operatively engage. The two worms h are both secured upon the same shaft 2' upon which is also secured a cam 76 which serves for moving the escapement rods Z out of and into operative position, this cam serving to rock an angle lever m about its pivot m As shown in Fig. 4, the cam 70 is provided with a peripheral depression in which the lever m rests when the machine is in operative position, i. c. when the escapement rods Z are, as shown in Fig. 1, in posi tion to engage the escapements of the respective magazine.

On the shaft 6 is secured a crank handle at by which it can be rotated, and when it is so rotated, the angle lever on will first be moved and thereby withdraw the escapement rods Z out of their operative position.

Each of the worms h. as illustrated in Figs. 2 and 3, a flat surface or portion 0 located in a plane perpendicular to the axis of the shaft 11, so that when this shaft is rotated anti-clockwise or clockwise in order respectively to lower or raise the magazines, the first part of such rotation will have no effect upon the column of magazines which, during that period, will remain stationary. Meanwhile, however, the angle lever m has completed its movement and the escapement rods Z have been withdrawn as before stated, and it is only when the fiat surface 0 has passed beyond the respective stud 9 that the actual shifting of the magazines commences. Each rotation of the shaft 7" withdraws the escapement rods Z asaforesaid, moves the column of magazines a dis tance equal to the thickness of a magazine plus the distance between any two adjacent magazines, and restores the escapement rods into their operative position.

Each of the disks 9 with its complement of studs 9 is herein regarded as a wormwheel and, for convenience, is referred to as such in the following claims.

Having described my invention, I declare that what I claim and desire to secure by Letters Patent is 1. In a multiple-magazine typographical composing machine, the combination with a column of magazines, and a worm-Wheel in operative connection therewith to shift said column, of a worm cooperating with the worm-wheel, and a flat surface on said worm, with which the teeth or studs of the worm-wheel engage at the commencement of the magazine-shifting operation, so that the worm can be partially rotated without shifting the magazines.

2. In a multiple-magazine typographical composing machine, the combination with a column of magazines, and a worm-wheel in operative connection therewith to shift said column, of a worm cooperating with the worm-wheel, a fiat surface on said worm enabling the worm to be partially rotated without shifting the magazines, escapement rods adapted to actuate escapements on the magazines and devices operating conjointly with the worm disengaging the escapement rods from and engaging them with the escapements during the periods at which the worm rotates without shifting the ma 'a zines.

3. In a multiple-magazine typographical composing machine, the combination with a column of magazines, and a worm-wheel in operative connection therewith to shift said column, of a worm cooperating with the worm-wheel, a flat surface on said worm enabling the worm to be partially rotated without shifting the magazines, escapement rods adapted to actuate escapements on the magazines and a cam operatively fast to the worm operative to disengage the escapement rods from and engage them with the escapements during the periods at which the worm rotates without shifting the magazines.

4. In a multiple-magazine typographical composing machine, the combination with a column of superposed magazines, a magazine frame supporting said column, a toothed rack attached to said magazine frame, a spur wheel engaging the rack and a worm-wheel operatively fast to the spur.

wheel, of a worm cooperating with the worm-wheel, a flat surface on said worm enabling the worm to be partially rotated without shifting the magazines, escapement rods adapted to actuate escapements on the magazines and a cam operatively fast to the worm operative to disengage the escapement rods from and engage them with the escapements during the periods at which the worm rotates without shifting the magazines.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
